file_statistics

The file_statistics module is used to check the format of: *.apdv; *.aidv; *.geo; *.gmf; *.vdf; and *.pgf files, and to calculate and display statistics about the data contained in these files. This module also calculates a frequency distribution of properties in the file. During execution, file_statistics reads the file, displays an error message if the file contains errors in format or numeric values, and then displays the statistical results in the EVS Information window
